Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510296, here are decompositions:

53 + 31510243 = 31510296
73 + 31510223 = 31510296
79 + 31510217 = 31510296
109 + 31510187 = 31510296
127 + 31510169 = 31510296
157 + 31510139 = 31510296
163 + 31510133 = 31510296
347 + 31509949 = 31510296

Showing the first eight; more decompositions exist.
